Atal Setu: Discover The Grandeur of India’s Longest 21.8km Sea Bridge

The Mumbai Trans Harbour Link (MTHL), popularly known as Atal Setu, is the longest sea bridge in India and a magnificent engineering achievement. Connecting Mumbai and Navi Mumbai, this 21.8-kilometer colossus was inaugurated in January 2024.

I am filled with pride and hope for the future of India as I reflect on the inauguration of Atal Setu. This amazing engineering feat spanning 21.8 km with a large portion over the sea is not just a bridge but a gateway to progress and development.

The Atal Setu inauguration marks a milestone in India’s infrastructure journey, demonstrating our country’s capacity to undertake and complete such large-scale projects. As the Prime Minister has rightly said, this bridge shows India’s infrastructural potential and signals our journey towards a ‘Viksit Bharat’ or a developed India.

Atal Setu will transform the lives of millions of people by reducing the commute time from 42 km to just 20 minutes from Mumbai to Navi Mumbai. This bridge will not only improve connectivity but will also open up huge economic opportunities in the region. The estimated daily movement of more than 70,000 vehicles will make Atal Setu a lifeline for millions of commuters, businesses, and industries.

Atal Setu also symbolizes our government’s commitment to infrastructural development. Not only did this project employ thousands of workers and engineers, but it also showed that our government is committed to nation-building.

Atal Setu is also strategically important. Not only will it connect Mumbai with Navi Mumbai, but it will also give faster access to important airports and ports. This will make it easier for trade and logistics to move around.

It will also strengthen the city transport infrastructure and improve connectivity with regions such as Pune and Goa, as well as South India, which will help in regional integration and boost economic growth in the country.

As we celebrate this amazing achievement, let’s also look forward to the future with optimism, for bridges like this not only represent steel and concrete but also symbolize our collective determination to overcome difficulties and build a better future for future generations.
